Answer:
a=1
b=2
c=-8
y-intercept: (0, -8)
Line of symmetry calculation: x = -2/(2*1)
Line of symmetry: -1
Opens up because a > 0
Minimum
Vertex: (-1, -9)
Domain: -∞ < x < ∞ (no domain constraints)
Range: [-9, ∞]

Answer:
B. Rational
Step-by-step explanation:
the square root of 25 is 5. 5 best fits the classification of rational
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
First term = 13
Increase each time = 20
Number of clients = 25
So, it forms an arithmetic progression:
So, 25 th term would be

Hence, list would look like 13,33,............493.
Therefore, Option 'D' is correct.
Answer:
x < -5
Step-by-step explanation:
Distribute 4 to x and 10: 4x + 40 < 20
Subtract 40 from both sides: 4x < -20
Divide by 4: x < -5
